Claims a new transcoding pipeline that converts raster video into SVG/WebGL-rendered vector animations, using Potrace, an MP4 container and a JavaScript/WebGL player and comparing against AV1 H.265 H.264 and VP9. Results show order of magnitude bitrate reductions for animated and screencast content — example: 4K Peppa Pig at 20 kbps. Prototype encoder is Python and runs at ~1 fps, and complex photorealistic clips fall apart (Big Buck Bunny requires ~12 Mbps). Practical limits include WebGL not DRM-compatible.
